Concatenated. The pressure shaping device P and the striping device C share a common power source, and are separated from their power transmission mechanism by the corner plate 1, thereby maintaining good sanitary conditions. The pressure shaping device P has a shaping roller 2 and a flat roller 3 below the shaping roller 2.

As is clear from FIG. 3, the straightening roller 2 has a plurality of shaping grooves 4 (three in the illustrated example) on its outer periphery, and an endless belt 5 is wound around each of these grooves 4 for approximately half the circumference. Can be hung. The endless belt 5 is wound around upper and lower pulleys 6 and 7 on the negative side of the shaping roller 2, and is maintained in its stretched state. Further, the starting end of the outward path of the endless flat belt B described above is wound around the lower end portion of the shaping roller 2. That is, the outward path of the endless flat belt B is from the pulley 8 disposed on the other side of the shaping roller 2, passes through the shaping roller 2, and reaches the pulley 9 disposed at the lower part of the side length device L, and the return path is from the pulley 9 disposed on the other side of the shaping roller 2. From there, it passes through the tension roll 10, the flat roller 3, and the pulley 11, and then reaches the pulley 8. At the end of the winding of the flat belt B around the shaping roller 2, the flat belt B is pressed against the shaping roller 2 by the flat roller 3. Shaping roller 2
A chute 12 is provided above. The chute 12 has a channel 13 corresponding to the shaping groove 4 of the shaping roller 2, and a water injection nozzle 14 is provided at each beginning thereof. Shoot 1
Three guides 15 and three pushing rollers 16 are disposed between the leading end of the flat belt B and the end of the flat belt B where it is wrapped around the shaping roller 2. The push roller 16 has a groove 17 in the width direction over the entire circumference. Gears 2B and 3C that mesh with each other are fixed to rolling shafts 2A and 3A of the shaping roller 2 and flat roller 3, respectively. As shown in FIG. 4, a transmission chain 19 is wound between a sprocket 2C provided on the shaping roller rotating shaft 2A and an output sprocket 18A of the clutch-brake reducer 18. Also, the shaping roller rotation shaft 2
A chain 21 is wound between the other sprocket 20 of A and the corresponding sprocket 20, and this chain 2
1 is the rotating shaft sprocket 16A of the pushing roller 16.
are engaged to rotate in the required direction. The above transmission system causes the shaping roller 2 and the flat roller 3 to rotate in opposite directions at the same circumferential speed, and also controls the pushing roller 16 and the like to rotate in the directions of the arrows in FIGS. 1 and 4. Note that the reducer 18 is connected to a drive motor (not shown) via a V-belt 22.
is linked to. Further, a transmission system consisting of a sprocket and a chain is also interposed between the respective rotating shafts of the pulley 9 and the flat rollers 3 and 0. The line cutting device C includes a plurality of presser frames 23 arranged in parallel at required pitches along the running direction of the endless flat belt B on the outbound side of the endless flat belt B, and a blade portion 24A between the presser frames 23. A comb-shaped cutter 2 having
4.

As shown in FIGS. 5 and 6, mounting plates 25A and 25B are protruded from the back surface of the partition plate 1 and are opposed to each other, and a pair of upper and lower rotating shafts 26 and 27 are mounted between these mounting plates 25A and 25B. It will be done. Eccentric shafts 26A and 27A are fixed to the upper rotating shaft 26 and the lower rotating shaft 27, respectively, in the same phase. A support frame 28 common to these eccentric shafts 26A and 27A
are mated so that only relative rotational sliding is possible. An arm portion 28A is integrally provided at the upper end of the support frame 28 and extends toward the surface side of the partition plate 1 through the verticalmost hole IA, and the cutter 24 is attached to the tip of the arm portion 28A. It is mounted via the mounting bracket 29 and screws 30 so that the level can be adjusted. On the other hand, a cam plate 31 is keyed to the upper rotating shaft 26, and an elevating plate 3 is located near the cam plate 31.
2 is placed. The elevating plate 32 is configured to be guided in smooth elevating and lowering by a slide bearing 33A provided between the elevating plate 32 and the mounting plate 25B. A cam roll 33 is attached to the elevating plate 32 in a cantilevered state, and this cam roller 33 is supported by the cam surface of the cam plate 31, while
In order to make the cam roller 33 always follow the cam plate 31,
A tension spring 34 is interposed between the elevating plate 32 and the mounting plate 25B. The upper rotating shaft 26 and the lower rotating shaft 27 are interlocked and connected so that they rotate in the same direction and in the same phase by meshing gears 268 and 27B attached to each with each other via the intermediate gear 35. . The lower rotating shaft gear 27B is then engaged with the output gear 36A of the clutch brake 36. As is clear from FIG. 1, the input to the input gear 36B of the clutch brake 36
The input is transmitted to the pulley 38 by the branching V-belt 37, and is transmitted via a gear 388 fixed to the rotating shaft 38A of the pulley 38. Therefore, when the output gear 36A and the input gear 36B of the clutch brake 36 are in a lotus joint state, the rotating shaft motion input through the gear 38B is transmitted to the upper rotating shaft 26 and the lower rotating shaft 27, and the eccentric The shafts 26A and 27A rotate in the same direction around their rotation axes while maintaining the same phase. Therefore, the cutter 24, which is interlocked and connected to the eccentric shafts 26A and 27A via the support frame 28, performs a circular motion as shown by the dashed line a in FIG. At this time, the bottom dead center of the cutter 24 is set so as to maintain a distance of one point from the flat belt B. This interval is necessary and sufficient to trim the shrimp S when they are fed on the flat belt B. On the other hand, the elevating plate 32 is
The action of a cam mechanism 39 consisting of a cam plate 31, a cam roller 33, and a tension spring 34 moves up and down as the upper rotating shaft 26 rotates, but the up and down movement is constant relative to the rotational movement of the cutter 24 around its axis. It is done in a timely manner. That is, after the cutter 24 starts circular motion from the state shown in FIG. 5, the presser frame 23 descends just before it comes into contact with the shrimp S, and in this state, after the cutter 24 cuts the stripes, the cutter 24 returns to the top dead center. It is set to rise just before.
Note that the flat belt B is supported by a support plate IB at the lower part of the thread cutting device C. Further, the presser frame 23 is attached to the tip of the arm portion 32A of the elevating plate 32 via a mounting bracket 40 and a screw 41 so that the level thereof can be adjusted. 42 is a second photoelectric detection device for detecting the positions of the eccentric shafts 26A and 27A.

In front of the line cutting device C, a first photoelectric detection device 43 is installed with the flat belt B and the partition plate 1 in between. This photoelectric detection device 43 is electrically connected to the speed reducer 18 and the clutch brake 36 . 44 is a horizontal level adjustment tool for the photoelectric detection device 43.

As shown in FIG. 1, FIG. 7, and FIG. 8, the side length device L includes a pair of endless belts 46 having a starting end roller 49A and a terminal end that are supported in a downward cantilever state on the front and rear ends of a mounting plate 48. Wrapped around the rollers 49B, their outward paths 46A
They are configured so that they gradually approach each other at first, remain parallel over a certain distance in the middle, and then move away from each other. The roller 50 that guides the outward path 46A has a concave outer peripheral surface. Therefore, the pair of endless belts 46 run in a cylindrical form in which the pairs of rollers 5 cooperate to form a cylindrical shape in the intermediate portion of the forward path 46A. The pulp transmitting device 47 includes a photoelectric device layer 51 disposed above and below the moving path of the shrimp S held between a pair of endless belts 46, and a pulse oscillator ( (not shown). The storage length device L is arranged such that the first half of the outward path 46A of the pair of endless belts 46 is located above the end of the outward path of the flat belt B, and the running speed of the endless belt 46 is equal to the running speed of the flat belt B. set equal. Note that 52 is a driving source. The sorting device D has a plurality of shrimp removing devices 54 arranged at required intervals along the outward path of the endless rotating body R.

These shrimp removing devices 54 are provided with a rotary solenoid 57 at the upper end of a support column 56 protruding from a machine frame 55 that supports the endless rotating body R, and a movable part 57A of the rotary solenoid 57 is provided with an endless An inverted T-shaped swing plate 58 is fixedly provided to be swingable in the width direction of the rotating body R. Stopper 5 on post 56
9 is fixed, and a spring 60 is interposed between the support column 56 and the swing plate 58 to bias the swing plate 58 in a direction in which the swing plate 58 is always supported by the stopper 59. Rotary solenoid 5
In response to the input signal, the movable part 57A of 7 momentarily rotates against the bias of the spring 60 so as to swing the swing plate 58 clockwise in FIG. Sandwich the machine frame 5
A jiyama board 61 is arranged on the opposite side of 5. Jiyama board 61
A conveyor 62 that runs in a direction orthogonal to the endless rotating body R is provided at a lower portion between the endless rotating body R and the endless rotating body R. This conveyor 62 is made up of a large number of round belts 62A arranged at regular pitches in the width direction, and leads to the next step, a battering device (not shown). Reducer with clutch brake 1
8 is the output shaft sprocket 18A of the reducer 18.
In this state, the shaping roller 2 rotates clockwise in FIG. 1 as described above, while the flat roller 3 and the pushing roller 16 rotate in the counterclockwise direction.

In this state, feed the raw shrimp S through several rows of channels 1 of the chute 12.
3, manually put the shrimp into the shrimp that matches the size of the shrimp, belly side up, and at the same time, water is sprayed from the nozzle 14.
The shrimp S are pushed through the flow path 13 by the water flowing through the flow path 13 and sent into a predetermined shaping groove 4 of the shaping roller 2. At this time, due to the rotation of the push-in loaf 16, the shrimp S is reliably pushed between the guide 15 and the shaping roller 2 without causing any slipping, and the shrimp S is pushed into the endless belt 5 within the shaping groove 4 while the passage is gradually narrowed. It is held between the flat belt B. By transferring in this state, the shrimp S are pressed and shaped. In this case, if the flat belt 45 is provided with a large number of unevenness, slippage between the shrimp and the shrimp can be completely prevented. Note that the water flowing down from the chute 12 is received by a water receiver 63 and collected. The final pressure shaping of the shrimp S is performed when the shrimp S passes through the portion where the flat belt B is pressed against the shaping roller 2 by the flat roller 3, and then the shrimp S is shaped into the shaping groove by the endless belt 5. 4 and sent to the liner C on a flat belt B. When the rear part (for example, the tail) of the shrimp S fed on the flat belt B is detected by the photoelectric detection layer 43, the lotus joint of the clutch-brake reducer 18 is switched in response to the detection signal.
That is, at the same time as the output shaft sprocket 18A stops rotating, the V belt 37 and pulley 38 start rotating, and the input gear 368 and output gear 3 of the clutch brake 36
6A is connected, and the presser frame 23 and cutter 24 of the device C start operating. That is, when the flat belt B stops running, the shrimp S waiting at the bottom of the line cutting device C is first lowered to hold the shrimp S at a plurality of locations, and then the cutter 24 moves in a circular motion. As it descends, the line cuts are made at multiple locations near the bottom dead center. After trimming, the presser frame 23 is raised and released from its pressed state. When the cutter 24 rotates once, the photoelectric calendar 4
2 detects the positions of the eccentric shafts 26A and 27A, and the clutch brake 36 is actuated by the detection signal, and the lotus joint between the input gear 36B and the output gear 36A is released, and at the same time, the clutch brake equipped reducer 18 is connected to the output shaft sprocket. Switch to 18A side. Along with this, the flat belt B starts running again, and the shrimp S after the striping is sent to the neck lengthening device L. In the column length device L, a pair of endless belts 46 are driven to run at the same speed and in the same direction as the flat belt B. Therefore, the shrimp S is transferred from the flat belt B to the cylindrical portion formed by the pair of endless belts 46, and is held and moved by this portion.
During this process, the length of the shrimp S is measured by a pulse oscillator that acts on the photoelectric device 51 for a certain period of time. The side length signal from the pulse transmitting device 47 is compared with the setting value of the side length unit, and converted by the determination circuit into a large, medium, small, or large/small discrimination signal. Side lengthened shrimp S
is continuously sent onto the endless rotating body R and reaches the sorting device D, while the discrimination signal is transmitted by a shift register and input to one of the three shrimp removing devices 54. The three shrimp removing devices 54 are large, medium, and large, respectively.
The rotary solenoid 57 corresponding to the small judgment signal operates and the shrimp S sent on the endless rotating body R is blown away by its swing plate 58.

The shrimp S thrown off in this way collides with the chopping board 61, becomes straight, falls straight down, rides on the conveyor 62, and is sent to the next process. As is clear from the above description, according to the present invention, pressure shaping, lining, and sorting of shrimp can be performed continuously, and each operation is performed in an extremely hygienic manner.
